Rear sight attachment for archery bows

ABSTRACT

An archery sight comprising an elongated bracket secured to the archery bow&#39;s front sight threaded bore, and extends rearward of the bow&#39;s riser. There being at the end of the bracket a 90 degree bend that forms a laterally extending shelf. The shelf has a slot into which is mounted a vertical standing rear sight pin that is shaped like the letter Y and is attached by means of threaded bore. By aligning the distal end of the selected front sight pin or pins (by others) into the exact bottom of the junction of the Y shaped pin, the bow man is able to control the course of the arrow quite accurately.

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of U.S. Provisional PatentApplication Ser. No. 60/222,633 filed Aug. 3, 2000.

1. FIELD OF INVENTION

[0002] This invention relates to aiming sights for archery bows, inparticular to a rear sight to be used with a front pin sight assembliesall ready in use on todays modern compound hunting bow.

BACKGROUND OF THE INVENTION

[0003] It is known that rear sights may be positioned on bows to aim thearrow shot therefrom. Rear bow sights are shown in U.S. Pat. No. Des.423,627; 4,159,575; 4,215,484; 4,977,678; 5,040,301; 5,864,958; and6,003,233, most being bulky in nature work inconjuction with their frontsight, sight assemblies. Many incorporate a rear aperture thatconstricts the users sight picture to intend target. Some rear sightshave cross hair type aiming points which are useless in low lightconditions. There are some rear sights with apendages bolted on thatwill vibrate loose. All of the current rear sights have a seperate rearguard that further inhibits the archers sight picture to the target.Many of these sights used require the archer to change his anchor pointto an uncomfortable position due to these sights limited adjustabilityto each individual archer.

[0004] It would be desirable, therefore to provide a light weight rearbow sight that can be used with a variety of front sights by othermanufactures. A rear sight that will eliminate the constricting natureof the peep or aperture sights. A rear sight that is fully adjustable tothe individual archer and can be locked securely in place. A rear sightthat enhances the users ability to shoot at targets or intended gameanimals in low light conditions and will mount on virtually all modernand early model archery bows.

[0005] The compound bow has been produced and long known to the priorart to be a difficult weapon to master the skill necessary to shootaccurately and consistantly. Modern hunting bows rely on a front pinsight assembly and a peep sight in the bowstring as a means of sightingin on the target at predetermined distances. Hunters have relyed onswinging pedulum sights to make shots at game from elevated standpositions. The pendulum type sights only work at certain stand heightsand angle to game on the ground. These pendulum sights try to compensatethe archer for poor bow placement caused by the angle to the game on theground.

[0006] Both pin and pendulum front sights require the use of a peepsight in the bow's string. Due to the difficulty in the human eyesability to center the front sights in the peep and on the target, theneed for a more accurate means of sighting and aligning the bow to theeye is well known to the art.

OBJECTS OF THE INVENTION

[0007] It is the object of the invention to provide an improved rearsighting option attachable to a variety of bows.

[0008] Another object is to not block the archer's view in aiming at atarget or hard to see animal.

[0009] Yet another object of the invention is to bring the eye to thetarget plane and arrow to target plane closer together for extremelyaccurate shot placement.

[0010] Still another object is to replace the string peep and swingingpendulum with a solid sighting system, incorporating front pin sightassemblies (by others) and the rear sight device of my invention.

SUMMARY OF INVENTION

[0011] My invention as seen in the illustration, is comprised of three(3) basic parts solidly attached to form a very rigid rear sightinganchor point.

[0012] The bracket has a unique 90 degree bend and adjustment slot whichallow the bracket to be mounted to the archery bow via mounting holes inthe bow. Angled cut sides and the 90 degree bend turns bracket acrossinside of the bows riser, to provide a narrow shelf to which the rearsighting stud is attached with a single nut.

[0013] The rear sight bracket may be lowered or raised to the preferenceof the archer and necessary clearances needed for the arrows fletchingto pass unrestricted underneath the bracket's tail section.

[0014] By bringing the bracket down as close as possible to the arrow,the archer is lowering the eye to the target plane closer to the arrow'sflight plane.

[0015] This produces a sighted in arrow that travels along a parrallelcloser to the eye's parrallel to the target. At the point where thearchery bow is at full draw (just before arrow is released) the nockingpoint on the bow string and the shooters aiming eye are for most archersfour to six inches apart, while aiming with a traditional “peep sight”.

[0016] My invention will bring the “eye to nock” distance to 1½ to 3inches. This will reduce the effect of the eye to target, arrow totarget planes crossing at distances beyond what the front pin sights areset.

[0017] Also because the archer is sighting along the arrow's flight pathfrom a fixed position on the archery bow. The archer will be able tomake downward angled shots at game animals form an elevated stand,because the eye to bow position will not change.

DETAILED DESCRIPTION

[0024] One (1) referring to FIG. 1, the rear sight bracket is a singlepiece of aluminum with slots 1 cut into the foremost part of thebracket. One or more slots will align with screw holes in the bow'sriser 2 of FIG. 2. This section of the bracket is in a vertical positionwhen mounted to the bow. In FIG. 4, the screws which mount front sightbracket 3 to the bow's riser 2 will pass threw slots 1 in the rear sightbracket and securely fasten bracket to bow.

[0025] As shown in FIG. 1, FIG. 2, and FIG. 4, the tail 4 extendsrearward from the riser 2 and has a 90 degree break or bend 5 and turnsacross the inside of the riser 2 horizontally and extends back towardthe string 6 as shown in FIG. 3. The 90 degree bend at 5 produces ahorizontal shelf and is a stiffener to eliminate horizontal and verticalshifting and bending of rear sight bracket.

[0026] Also there is a single slot in the tail section 4 for mountingand adjusting the rear sight stud 7 from left to right as determined bythe preference of the archer.

[0027] On the tail section 4 there is a rubber string guard 8 that actsas a serving point where the string 6 will release the arrow inprecisely the same point everytime. The rear sight stud 7 has a flatseat 8 as shown in FIG. 6 and is threaded about three eighths of an inchup from stud seat 8, then tapers down to form a small conical pin shape,the end of which has an enlarged head shaped like letter the V9. Thereis a small hole drilled at the exact bottom of the V9. The hole willaccept fiber optic material to allow the archer to make shots at gameanimals in low light conditions.

[0028] Referring again to FIG. 6, the rear sight stud 7 is placed upthrew the slot 10 in the tail section 4 of the bracket and is securedwith nut 11 which passes down over the head and tapered portion of thestud 7 to secure to the threads extending threw the slot 10 in the tailsection 4 bracket slot 10.

[0029] To achieve proper bow placement in the archers hand, it isdesirable that the rear stud 7 is placed in a position in the tailsection slot 10 so that when aligning the rear sights V shaped stud head9 with others front pin sight 13, FIG. 4 and target at bows full draw,no noticable canting or wrist twisting is felt.

[0030] Referring to FIG. 3, the rear sight is adjusted vertically byloosening mounting screws 12 in the bows riser 2 and raising or loweringentire rear sight bracket and allowing rear sight bracket to slide alongscrews 12 by slots 1 in riser end of bracket.

[0031] As seen in FIG. 5, the rear sight bracket can be lowered to aposition to allow clearance of arrow's 14 fletching 15 but not allow anycontact between arrow's fletching 15 and rear bracket.

[0032] Retighten screws 12 in rear sight bracket. After positioning rearbracket, all adjustments made to zero in arrow 15 to intended targetwill be made by adjusting front pin sights (by others) left or right andvertical up and down until arrows are striking the intended impact pointon the target, at known distance.
